Fiber Media Converters are critical in networks where fiber needs to be integrated with different kinds of cabling, such as copper or serial, to optimize performance, cost, and scalability. They convert the electrical signals used in these other types of cables into the light waves used in multimode or single mode fiber optic cabling, and vice versa.
Fiber Media Converters are also used to extend the data transmission distances of a fiber network by linking multimode to single mode or simply joining two multimode cables together.
Perle Systems designs and manufactures the most extensive Fiber Media Converter offering in the world. Use the quick links below to learn more about the various types of fiber media converters, the devices they can connect to, and the diverse environments in which they operate.
PSI-MOS Serial to Fiber Converters transparently connect RS232, RS422 and RS485 devices to fiber optic cable. By transmitting data over optical fiber, these serial media converters provide an economical path to extend the reach of serial devices.
